We have installed 6 Relion 100ah LIFPO4 batteries a year ago, we plan on boondocking. They have performed well so far and have battery management internal to them. They have good cold weather ratings. As previously mentioned, you must change your converter to Lithium setting so the charging algorithm is acceptable for the lithium battery chemistry. It will not damage the battery if you don't, but will not completely charge the new battery. The upside is wet batteries can only be discharged 50% whereas lithium can discharge to 10% capacity safely. You get a lot of extra battery for the space and money.
